Abstract
The voltage step-up characteristics of the Rosen-type piezoelectric transformers using Pb(Mn/sub 1/3/Sb/sub 2/3/)O/sub 3/-PbZrO/sub 3/-PbTiO/sub 3/ ceramics were investigated as a function of the width (W) and length (L). Two types of PT were prepared in this study; one type with W>L and the other with WL.
